Abstract

The interaction between the osmium clusters [Os₃(CO)₁₂], [Os₃(CO)₁₀(μ-H)₂], [Os₃(CO)₁₀(μ-H)(μ-OH)], and a series containing a free functional group, viz., [Os₃(CO)₁₀(μ-H)(μ-S^∧ EH)] (where ^∧= alkyl chain or an aromatic ring, E = COO, S or O), with SiO₂, ZnO and In₂O₃, was examined by ToF-SIMS and IR spectroscopy. While the interaction with the silica surface is mostly via an O atom or the functional group, the interaction with the ZnO and In₂O₃ surfaces is more complex.
